The concept of “super-resolution” was born, and in the cur- rent literature it is generally associated with various meth- ods for improving the angular resolution of an optical imag- ing system beyond the classical diffraction limit. In the mi- crowave range, the first successful laboratory test of TPs was performed in 2003. These first results suggested that TPs could represent a viable approach to achieve super- resolution in Radio Astronomy. We have therefore started a project devoted to an exhaustive study of TPs and how they could be implemented on a radio telescope. In this work we present a summary of the status of this project, and then we describe a preliminary design to implement a TP system on a 32-m radio telescope. | Titolo del convegno: | XXXIInd URSI General Assembly and Scientific Symposium (URSI GASS 2017) | Luogo del convegno: | Montreal, Canada | Periodo del convegno: | 19–26 August, 2017 | URI: | http://hdl.handle.net/20.500.12386/29982 | URL: | https://www.ursi.org/proceedings.php http://www.ursi.org/event.php?id=331 |
